Worked: (optional)

Short description of error
Look at attached pictures. I am using Texture coordinates node (Normal output) to influence noise texture, which is then connected to bum map node. In viewport it works OK. In render, no bump map visible.

Exact steps for others to reproduce the error
Check attached blend file. It is fairy simple. Just compare Look Dev mode, with rendered mode.
